Data set Documentation
Abstract
This dataset contains microtremor horizontal-to-vertical spectral ratio (mHVSR) measurements taken along the Adriatic coastal plain in the two paleovalley systems of Pescara and Manfredonia. The measurements were acquired to stay near as possible to pre-existing geological data and, at the same time, far from every possible noise source. The H/V curve was processed the data with the Grilla software. Each three-component time series was split into non-overlapping windows of equal length (30 s). Fourier spectra were computed for each time window and smoothed with triangular functions having a width equal to 10% of the central frequency. We obtained the mHVSR curves by averaging the mHVSR ratios computed for each window, H being the geometric average of the instrumental N-S and E-W components.  The individual spectral components and mHVSR were calculated in terms of average ± standard deviation; transient perturbations were carefully removed by manual selection.
Content of the files
The .asc files contain HVSR measurements obtained at the Pescara or Manfredonia site. Every measure has a specific and unique name associated with unique geographic coordinates. Refer to the table in section “Data sources” for every coordinate.
Frequencies, expressed in Hz, are in the ASCI file's first column. The second column and the third column show HVSR and Standard deviation, respectively.
Data sources 
In the following table are shown the geographic coordinates of the sites where the HVSR measurements were taken.
